  1. What is Propulsion? “Propulsion means to push forward or drive an object forward. On airplanes, thrust is usually generated through an application of Newton's third law of action and reaction.” ScienceMaster

  2. Electrical Motors Electric power is a popular method of power and offers clean, quiet, and easy operation. Example of an electric motor

  3. Rotary engine Gas engine Intake Compression Power Exhaust A diesel engine works on the same principle as a gasoline engine, except instead of a spark plug there is a glow plug.

  4. also called gas turbines engine sucks air in at the front with a fan air is compressed by a compressor which is made up of fans with many blades attached to a shaft) blades compress the air compressed air is then sprayed with fuel and an electric spark lights the mixture burning gases expand and blast out through the nozzle in the back of the engine As jets of gas shoot backward engine and aircraft are thrust forward Jet Engines

  5. Types of Jet Engines Turbojet Turboprops Turboshafts Turbofans Ramjets

  6. Jet Engines

  7. A rocket engine works like a jet engine, except that a rocket carries its own oxygen or other oxidizer on board, so it can work in airless space. There are two main type rockets: liquid-fuel and solid-fuel.

  8. Did you know? Nuclear energy is the largest source of clean-air, carbon-free energy in North America. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. Question: What are the disadvantages of Nuclear Power?

  9. Solar Power Photovoltaic devices are solar-powered batteries that consume sunlight which make them a reliable, renewable and cost efficient way to produce energy. The Sun Photovoltaic is a modular system whose output can be engineered for almost any application including low-powered wristwatches and calculators to generating power at electric utility central stations and powering autos.
